| Question | Answer |
|---|---|
| What moves water into the atmosphere | Evapotranspiration |
| What are the five processes involved in the hydrologic cycle? | precipitation, evaporation, infiltration, runoff, transpiration |
| Drainage basins are separated from one another by | divides |
| Order from smallest particles to the largest | dissolved, suspended, bed |
| Where does a point bar accumulate | on the inside of a meander |
| In a channel, where is flow velocity the fastest | near the outside bank of a meander |
| How are natural levees formed | Suspended load is deposited when the river covers the floodplain |
| why does water released from a dam erode the streambed so much more than it would have before the dam existed | the stream power now exceeds the sediment load by a great amount |
| what is a playa | a salty, shallow lake |
| streams transport ions in solution as | dissolved load |
| The landform produced when a stream enter into a lake, reservoir or sea is called a | delta |
| When a stream's discharge decreases from bankfull discharge, it has appropriate power to | not transport all of its sedient load and deposits part of it |
| All of the following human activities the sediment load in a river except | converting cropland to natural vegetation |
| Deep incised river canyons most lieky form through some combination of tectonic and climate change that resulted in precipiation | uplift, more |
| which statement about ground water is false | it is pure h20 |
| ground water | percolates deep below the surface through open spaces and fractures |
| what lies just above the water table | an unsaturated zone |
| which of the following cause the ground water to flow | potential energy and pressure |
| a water well is contaminated by a nearby pollution source. A consultant suggests drilling a second well to help purify the first well. evaluate. | the strategy can work if the new well is pumped at a high rate to create a cone of depression deep enough to divert the polluted water |
| which is not a reason that fresh water wells near coastlines abruptly become salty and unusable | As water is pumped from the well, the freshwater runs out and leaves only the salty water from the sea |
